    Consider Your Roof Space:

In Canberra, solar panels are most effective when facing north, but east and west-facing roofs can also generate substantial energy. Additionally, shading from nearby trees or buildings can impact your system’s performance. Make sure your roof has enough space to accommodate the desired number of solar panels.

    Determine Your Budget:

    Solar systems come in various sizes and price ranges. Consider your budget and financial goals when deciding on the system size. Keep in mind that while larger systems may have a higher upfront cost, they can generate more energy and provide a faster return on investment through reduced electricity bills and potential government incentives.

    Calculate the Solar System Size:

    In this case, an 8 kW solar system would be suitable for your home in Canberra.

    Consult a Professional:

    It’s advisable to consult with a local solar installer in Canberra who can provide a detailed assessment of your energy needs, roof suitability, and budget constraints. They can help you choose the right solar system size and provide information about available incentives and rebates.
